Most literature that examines MPD focuses on the treatment of individual clients and only occasionally discusses the use of marital therapy as a supplemental form of treatment. We propose that marital therapy is a critical part of working with MPD patients in that it increases the speed and effectiveness of individual therapy and solidifies gains made with integration. The fallowing specific marital issues are examined: (1) educating the spouse, (2) understanding seepage (affective pervasion), (3) handling conflicting demands of alters, (4) responding to child alters, (5) supporting the sexual relationship, (6) adjusting to integrations, and (7) having patience with the therapeutic process. In addition, both marital therapy techniques and goals are examined in detail.
